You can grant user roles into Virtual Machines for AppController with following script:

1
2
3
4
5
6
7
8
9
$VMs = Get-VM
foreach ($VM in $VMs)
{
	$UserRole = $VM.UserRole.Name
	$UserRole = Get-SCUserRole -Name "$UserRole"
	$UserRoleID = $UserRole.ID.Guid
	$UserName = $VM.Owner
	Grant-SCResource -Resource $VM -UserName $UserName -UserRoleID @("$UserRoleID")
}

That will apply VM’s owner and UserRole as a granted user role.

You may see duplicate VMs in SCVMM 2012 R2 after a host crash in a cluster.

In that use you can use following script:

1
Get-VM "DuplicateVM" | Where Cloud -eq $Null | Remove-VM -force

That will remove that VM from SCVMM database only. VM will be online on host after operation.

You can use this script to move your VMs into another Cloud (Cloud Migration) on SCVMM 2012 R2.
This script only works on SCVMM 2012 R2 due to vHBA control.
You can remove vHBA control to make it work on SCVMM 2012 SP1.

You can use following script to see if remote host has cluster service:

$Servers = Get-Content C:\Servers.txt
foreach ($Server in $Servers)
{
	try
	{
		$State = (Get-WmiObject -ComputerName $Server -Class Win32_service | Where Name -like *clu*).State
	}
	catch
	{
	}
 
 
	if ($State)
	{
		Write-Warning $Server
		Add-Content -Value $Server -Path C:\ClusterResults.txt
	}
	else
	{
		Write-Host $Server
	}
}

Script will output all results into C:\ClusterResults.txt.

		Add-Content -Value $Value -Path C:\Results.txt
	}

You can type your servers into C:\Servers.txt and check WBEM status.

$Servers = Get-Content C:\Servers.txt
foreach ($Server in $Servers)
{
	try
	{
		$TestWBEM = (Get-Item "\\$Server\C$\Program Files\HPWBEM\Tools\HPWbemTestEvent.exe" -ErrorAction SilentlyContinue).Exists
	}
	catch
	{
	}
 
	if ($TestWBEM -eq $True) { $TestWBEM = "True"; } else { $TestWBEM = "False"; }
 
	$Value = $Server + ";" + $TestWBEM
	Add-Content -Value $Value -Path C:\Results.txt
}

That will export all data into C:\Results.txt.

You can add DVD devices into SCVMM 2012 R2 templates with this script:

1
2
3
4
5
6
7
8
$Templates = Get-SCVMTemplate
foreach ($Template in $Templates)
{
	$JobId = [System.Guid]::NewGuid().toString()
	New-SCVirtualDVDDrive -JobGroup $JobId -Bus 0 -LUN 1 
 
	$Template | Set-SCVMTemplate -JobGroup $JobId
}

All DVD devices will be on “Bus 0, Lun 1”. You can change it for different location.
